"Purchasing power parity" is a non-concept for almost 100% of companies and products. But YouTube Premium is priced differently in different regions. Sometimes much cheaper than $14.
The person you're responding to is not debating that the companies are setting the wrong prices, so no need to try to convince them that the companies are already setting prices "the right way".
